A method for regulating a kinematic variable of a motor vehicle. The method includes: receiving actual value signals, which represent an actual value of a kinematic variable of a motor vehicle; receiving setpoint signals, which represent a setpoint value of the kinematic variable; ascertaining an actuating variable to be implemented by one or multiple actuating element(s) of the motor vehicle, based on the actual value, the setpoint value and a variation of the setpoint value over time in such a way that a deviation between the actual value and the setpoint value becomes smaller when the actuating variable is implemented with the aid of the one or multiple actuating element(s); and outputting actuating variable signals, which represent the ascertained actuating variable. A device, a computer program, and a machine-readable memory medium are also described.

Method for regulating a kinematic variable of a motor vehicle

A braking device for a motor vehicle has a setpoint controlled deceleration device, which, upon receipt of a braking request input by a driver or an assistance system, for example, on the basis of a difference between a setpoint value and an actual value, drives a brake of the vehicle to generate a setpoint controlled braking torque for a deceleration of the motor vehicle. In addition, the braking device has a braking preparation control, which, upon receipt of a braking preparation signal, drives the brake independently of the setpoint value to produce at least one braking pressure for generating a preparation braking torque for a pre-deceleration of the motor vehicle. The braking preparation signal is generated as soon as a driving situation is ascertained where a braking request input by a driver or an assistance system is very likely imminent.

Braking device for a motor vehicle having preparatory pre-deceleration and method for controlling such a braking device

A method for holding a vehicle at a standstill includes a first phase in which the brake pressure at the wheel brakes is retained so that the vehicle is held automatically by the service brake, and the braking force is then transferred to a parking brake so that in a second phase the vehicle is held solely by the parking brake. A risk inherent in this transfer is that the vehicle may begin to slip. The distance over which the vehicle slides in uncontrolled fashion can be made substantially shorter if, in the second phase in which the vehicle is being held by the parking brake, the movement of the vehicle is monitored by sensors, and brake pressure is automatically built up by way of an actuator as soon as the fact that the vehicle is rolling away has been detected.
